Thank you very much for putting this thread together TitaniumCranium, I have been in bimmerforums for a while and found this after hours of searching for info on this swap. I am going to be doing this in my e39 in a few months and will need all the help I can get

Give me a shout when you get to the point you need assistance. I'll help you however I can.

In fact, I'll help anyone attempting this in any way I can. It really is one very intense puzzle! I'm an IT guy - I love puzzles!!!
